The continued use of arsine gas and/or its derivatives is vital to the manufacture of a wide variety of semiconductor devices. While the use of arsine is growing, it poses serious environmental and safety problems in the industry. New methods must be found that permit the facile trapping and detoxification of arsine and its derivatives. Advanced Technology Materials, Inc. (ATM) has gained a reputa ...

The potential applications of microelectromechanical systems (MEMS) have only begun to be recognized. This technology demands thin film materials with exceptional microstructural quality for high performance and processes with high yields. For piezoelectric microactuator applications, thin film lead zirconate titanate (PZT) is the leading material choice. Furthermore, substitutional modificatio ...

Multilayer thin films deposited onto Si wafers often exhibit high residual stresses during processing, leading to structural failure and/or electrical breakdown. Traditional scanning x-ray diffraction provides an accurate measurement of complex stress behavior in multilayer structures, but is difficult to carry out on a routine basis. Laser deflection methods are easy to perform but provide a li ...

THE UNIQUE PROPERTIES OF SEMICONDUCTING DIAMOND MAY BE EXPLOITED TO CREATE NOVEL, COMPACT, LOW-NOISE PHOTON AND PARTICLE DETECTORS. PHOTOMULTIPLIER TUBES ARE THE DETECTOR OF CHOICE WHEN LIGHT LEVELS ARE LOW OR WHEN THE PROPER SIGNAL MUST BE EXTRACTED FROM A CLUTTERED BACKGROUND. CONTINUOUS DYNODES, KNOWN AS CHANNEL ELECTRON MULTIPLIERS, ARE WIDELY USED AS PARTICLE DETECTORS. INNOVATIVE CHANGES ...

Sensors and control electronics based on SiC offer an opportunity to realize systems with operating temperatures approaching 500 degrees C. The unique high temperature properties and chemical robustness of SiC make it an ideal choice for applications where generic components and sensors need to function under widely varying environmental conditions The wide range of environments in which military ...

A $1B commercial blue optoelectronics industry supplying full color displays, high speed communications systems, and high density optical recording devices will happen. The question is: which technology, II-VI materials, III-V nitrides, or silicon carbide and its alloys, will dominate? Theoretical calculations and experimental external quantum efficiencies combined favor a direct band gap material ...

Although imaging in the 8-12 micron spectral region has widespread uses, high background radiation result sin low contrast, and charge storage in SiO2 capacitors limits the signal-to-noise and the upper limit of the dynamic range. A major opportunity exists to increase the performance of IR focal plan arrays (IRFPAs) using high dielectric constant BaSrTiO3 (BST) films to increase charge storage at ...

We propose to develop manufacturable high-temperature superconducting (HTS) Josephson junctions on silicon substrates. This technology will make available a wide range of silicon fabrication methods, allowing superconducting and semiconducting circuit elements on the same chip. The ultimate goal is to provide high performance monolithic rf components combining active and passive superconducting co ...
